Abstract

Purpose Social scientific research is having a substantial impact on eyewitness identification procedural reforms. Police agencies in the USA have changed their eyewitness practices based on the results of social scientific research. The purpose of this paper is to contribute new knowledge by using a unique set of data to describe detailed aspects of eyewitness identification procedures conducted as part of robbery investigations in Houston, TX. Design/methodology/approach Robbery investigators completed surveys following identification procedures conducted during a six-month period of time. The sample includes 975 identification procedures. The analysis describes important features of identification procedures and places results in the context of existing research. Findings Results show that photo spreads were the most frequently used lineup procedure and selection outcomes were similar to recent field studies conducted in the USA. Results also show that the type of procedure, presence of a weapon, cross-race identifications, and viewing opportunity were significantly correlated with selection outcomes. Originality/value Police are reforming their eyewitness identification procedures based on findings from social science research. The study measures and describe the characteristics of a large sample eyewitness procedures conducted by investigators in the field.
